Abstract: ABSTRACT OF THE DISCLOSURE           A warning system and ram saver for a blow out preventer includes a control cylinder connected to the lines supplying hydraulic fluid to the blow out preventer, and a pneumatic diverter valve connected to the hydraulic cylinder.  The diverter valve is in the air line between the air clutch control valve and supply for the drum clutch, which operates the main hoisting winch to move the drill string through the blow out preventer.  When the blow out preventer is closed and the drum clutch control valve is opened in an attempt to operate the main hoisting winch, the diverter valve prevents air flow to the drum clutch and causes the air to flow to a horn, which provides a warning that the blow out preventer is closed.

Abstract: METHOD AND APPARATUS FOR SORTING CORNER POINTS        IN A VISUAL IMAGE PROCESSING SYSTEM            ABSTRACT OF THE DISCLOSURE             Method and apparatus is disclosed for automatically processing visual images electronically so as to permit intelligent machine analysis of the image content.  A special distributed logic system architecture facilitates rapid real time image analysis and the production of reaction control signals in a high speed production line environment, for example.          Dedicated decision logic is employed to determine in but a single micro-instruction cycle whether a detected corner point of the image should be linked to another already linked chain of such corner points so as to define part of a closed edge contour of the image under examination.  This ability to so rapidly classify encoded corner points as either belonging or not belonging to a given set of such corner points which describe a closed edge contour is quite useful in achieving rapid real time image analysis capability. Special dedicated data address indexing circuitry is also employed for most expeditiously retrieving successive address linked data words from a data memory in successive single micro-instruction cycles as required to take full advantage of the high speed dedicated corner point matching circuitry.          The dedicated data memory indexing circuitry is provided in addition to the usual program instruction indexing circuitry employed in connection with the instruction register of the associated data processing system.

Abstract: Abstract A circuit for changing the frequency of a pulse train in response to a change in the average value of an applied digital signal applies the signal to be changed to a pulse subtractor.  Application of a predetermined number of digital data signals of one sign causes the periodic subtraction of the pulse at the subtractor, thus reducing the average freguency at the output from the pulse subtractor.  The signal at the output from the subtractor is applied to a pulse adder which adds a pulse to the subtracted pulse trained in response to a predetermined number of data pulses of the opposite sign.   The output pulse train is thus varied in frequency in response to variation in the average value of the digital data input.  The order of addition and subtraction may be reversed, and one of the functions can be performed in the feedback loop of a frequency synthesizer.
